Biozen WCX<br class="t-last-br" />
Biozen WCX HPLC columns consist of non-porous polymeric particles that can separate proteins from their acidic and basic variants
Biozen WCX
Biozen WCX
Biozen WCX was constructed with linear polycarboxylate chains grafted to monosized non-porous polymeric particles, to sinuously envelop and separate proteins from acidic and basic variants. With a highly tuned and controlled manufacturing process, Biozen WCX affords scientists a way to reproducibly characterize heterogeneity with an added advantage of excellent recovery using bioinert titanium column hardware.

Charge Variant Analysis
bioZen WCX was crafted to consistently decipher between native protein variants that arise from PTMs within a therapeutics creation and development. The linear polycarboxylate chains grafted to monosized non-porous polymeric particles, envelop and separate proteins from acidic and basic protein variants. With such a highly. tuned and controlled manufacturing process, bioZen WCX media affords scientists a way to reproducibly characterize heterogeneity while taking advantage of excellent recovery through high particle inertness and bioinert titanium BioTiâ„¢ column hardware.

Native Mode Mass Spectrometry with bioZen WCX
Ion-exchange chromatography (IEX) is a technique employed in the characterization of biotherapeutics under nondenaturing conditions. Standard mobile phase conditions for these techniques are high in salt concentration, rendering them incompatible with mass spectrometry (MS) detection. Native MS represents a cutting edge approach to employ MS compatible mobile phases for non-denaturing IEX analysis. Observe and measure the non-covalent interactions and charge variants of proteins at high resolution using bioZen WCX.
